Intel’s latest roadmap reveals three
new Penryn
based Xeon models with a higher front-side bus speed – 1600
MHz. The three new 1600 MHz front-side bus processors are available
in dual-core and quad-core models. Quad-core Xeon E5472 and E5462 are
the first quad-core models to receive the 1600 MHz front-side bus
treatment.

The Xeon E5472 features a 3.0 GHz clock speed while
the E5462 features a 2.8 GHz clock speed. These models feature
80-watt thermal ratings as designated with the E moniker. Intel plans
to release these 1600 MHz front-side bus processors in Q4 2007 with
the rest of the Penryn family.

Pricing for the 1600
MHz front-side bus processor starts at $797 for the E5462 and $958
for the E5472, per processor, in 1,000 unit quantities. As far as
pricing goes, the Xeon E5472 slots below the 3.16 GHz X5460 while the
E5462 slots below the 3.0 GHz, E5450.

Intel has one 1600 MHz
dual-core Penryn based Xeon processor ready for launch – the
E5272. The Xeon E5272 features a 3.4 GHz clock speed and is priced at
$1,172. Intel has also pulled in the launch of all dual-core Xeon
processors to Q4 2007, with the quad-core processors. The dual-core
Xeon E5260 and E5205 will also launch
in Q4, not the Q1
2008 date earlier roadmaps showed.

Intel 1600 MHz
front-side bus Xeon processors will drop into the upcoming Seaburg
chipset. Seaburg features support for dual PCIe 2.0 x16
slots and up to 128GB of memory.
